- The proximal convoluted tubule (PCT) is a small tubular structure within the nephron of the kidney.The PCT connects Bowman's capsule with the proximal straight tubule, and it is essential for the reabsorption of water and solutes from filtrate within the nephron.he proximal convoluted tubule (PCT) is a small tubular structure within the nephron of the kidney.

Proximal tubule Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries. This is driven by sodium transport from the lumen into the blood by the Na+/K+ ATPase in the basolateral membrane of the epithelial cells.Sodium reabsorption is primarily driven by this P-type ATPase.he proximal tubule as a part of the nephron can be divided into two sections, pars convoluta and pars recta. Differences in cell outlines exist between these segments, and therefore presumably in function too.

The Renal Tubule: Definition, Function & Terms Proximal Convoluted Tubule. The filtrate in the Bowman's space I just mentioned enters the first duct in the renal tubule. This duct is called the proximal convoluted tubule, which is a section of the renal tubule located in the kidney's cortex that is responsible for the reabsorption of the majority of ultrafiltrate.he word 'proximal' in 'proximal convoluted tubule' implies it's near or attached to the renal corpuscle, and if you look at the image on your screen, you can also see how convoluted this duct is due to a bunch of twists and turns.

Proximal tubule Parathyroid hormone reduces reabsorption of phosphate in the proximal tubules, but, because it also enhances the uptake of phosphate from the intestine and bones into the blood, the responses to PTH cancel each other out, and the serum concentration of phosphate remains approximately the same.luid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries. This is driven by sodium transport from the lumen into the blood by the Na+/K+ ATPase in the basolateral membrane of the epithelial cells.

Filtration and Reabsorption The DISTAL CONVOLUTED TUBULE is where the final ajustments are made to the passing urine within the tubule systems. This is where highly selective reabsorption takes place allowing for small adjustments to be made especially between the presence of Potassium and Sodium.his commonly occurs throughout the entire nephron system especially within the Glomerulous and Bowman's Capsule where water, nitrogenous wastes, glucose, amino acids, vitamins, minerals, bicarbonate ions and hormones.

- 1 A proximal convoluted tubule drains filtrate away from a renal corpuscle. 2  A loop of Henle descends into the medulla, makes a hairpin turn, and returns to the cortex. 3  The distal convoluted tubule passes near to the original corpuscle (at the juxtaglomerular apparatus), then leads to a collecting duct.

The Structure of a Kidney Nephron The renal tubule is the part of the kidney nephron into which the glomerular filtrate passes after it has reached the Bowman's capsule. The first part of the renal tubule is called the proximal convoluted tubule (PCT), which is shown on the right-hand side of the diagram above.ithin the glomerulus are glomerular capillaries that are located between the afferent arteriole bringing blood into the glomerulus and the efferent arteriole draining blood away from the glomerulus. The (outgoing) efferent arteriole has a smaller diameter than the (incoming) afferent arteriole.
